Subject: [PATCH v2 1/2] ALSA: Kconfig: add config menu for reduced memory footprint
For some embedded devices, we need reduce code size and data
footprint as much as possible, e.g. disabling procfs, hw/sw
params refinement, mmap, dpcm, dapm, compressed API...
Here add root config menu for those configuration, and
disable procfs once reduced memory footprint is selected.
